Full Stack Developer

Overview

BigBear.ai is standing up a small, elite development team to deliver cloud-native applications that directly support mission operations. This is a focused, high-impact environment where your work is highly visible and directly influences outcomes. I’m looking for a Full Stack Developer with deep Python expertise and strong frontend craftsmanship who thrives in classified environments and brings a disciplined engineering mindset to building secure, maintainable systems under real operational pressure.

• What We’re Looking For
• Backend (Python): Strong Python development experience with Django (or equivalent), modern API design, Pydantic-style validation, and async Python in production
• Frontend (React/Next.js): Ability to deliver polished, responsive production UIs with thoughtful component design, effective state management, and strong UX attention
• Databases (PostgreSQL): Schema design, query optimization, migrations, and data loading/transformation (Aurora experience is a plus)
• Identity & Access: Hands-on integration of Keycloak and standards such as OIDC, SAML, JWT sessions, and CAC/PIV; strong understanding of RBAC and secure auth flows
• Cloud (AWS): Practical experience deploying, operating, and troubleshooting cloud-native apps across classified partitions; familiarity with EKS, Aurora, S3, IAM, VPC, KMS
• Infrastructure-as-Code: Comfort writing and maintaining Terraform modules
• Secure Engineering: Experience building software for STIG-hardened, FIPS-validated environments; strong grasp of least privilege, secrets management, and secure SDLC practices
• DevSecOps: Ability to interpret and remediate scan findings (SAST, DAST, SCA, container scanning, SBOM verification)
• AI-Assisted Development: Regular use of AI-enabled tools in daily engineering work, with an understanding of strengths/limitations

What you will do

In a typical week, you may:

• Extend a Django-based API gateway and services using modern API patterns (including Backend-for-Frontend)
• Build and refine React/Next.js interfaces and dashboards for operational workflows
• Design PostgreSQL schemas, tune queries, and develop migrations to modernize legacy data
• Integrate authentication/authorization using Keycloak (OIDC/SAML), including RBAC and secure session/token handling
• Deploy and operate applications across multiple AWS partitions and classification levels
• Contribute to infrastructure-as-code (Terraform) and CI/CD (GitLab) in a DevSecOps pipeline
• Use AI-assisted development tooling as a standard part of your day-to-day workflow to improve velocity and quality

What you should have

• Must have an active TS/SCI clearance
• 5+ years of hands-on software development (or equivalent demonstrated capability)
• Python backend development (Django, FastAPI, or similar; async/ASGI; modern Python)
• Frontend development with React, Next.js, or equivalent (production systems-not prototypes)
• REST API design including Backend-for-Frontend patterns and strong schema validation practices
• PostgreSQL schema design, optimization, migrations, and data loading
• AWS experience delivering and operating applications (including classified partitions/regions) Terraform (IaC)
• Keycloak and/or OIDC/SAML/CAC-PIV authentication integrations
• Secure development in STIG-hardened, FIPS-validated environments
• GitLab CI/CD and Git-based workflows
• DevSecOps scan remediation (SAST/DAST/SCA/SBOM/container scanning)
• Daily use of AI-assisted development tools

What we'd like you to have

• Building GenAI features into applications (RAG, LLM integration, embeddings/search)
• Legacy system/data migration into modern cloud-native architectures
• Kubernetes/EKS and Helm
• Hardened container supply chains and FIPS-validated image pipelines
• Practical application of NIST 800-53 controls to software design
• Multi-classification / cross-partition deployment architectures
• Experience supporting IC or DoD mission systems
